Details: http://sigrok.org/wiki/Fx2lafw
This new driver (+ firmware) currently supports the following devices:
- ARMFLY AX-Pro
- Braintechnology USB-LPS
- EE Electronics ESLA100
- EE Electronics ESLA201A

Only acquisition with 8 probes is supported so far. Support for 16 probes
and support for analog signal acquisition (on devices which have these
capabilities) will be added later.
* ASIX SIGMA driver:
- Add support for the ASIX SIGMA2. This requires the latest version of
the SIGMA/SIGMA2 firmware files.
Details: http://sigrok.org/wiki/Firmware

default (was $prefix/share/libsigrok/firmware before).
* Fix a Makefile.am bug which caused the generated ChangeLog files being
accidentally deleted upon 'make distclean'.
* ChronoVu LA8 input file format: Improve autodetection of the file format.
We now only accept files of the size 8388613 bytes (all LA8 files have
exactly this amount of bytes).
